You are considering purchasing a compact washing machine, and you have the following information: • The Energy Guide claims an estimated yearly electricity use of 350 kW-hrs, based on 8 loads of laundry being washed per week. • The Energy Guide claims an estimated yearly operating cost of $38. This estimate is based on $0.1065 per kW-hr, and eight loads of laundry being washed per week. • Local electricity costs $0.086 per kW-hr. • You wash four loads of laundry per week. Based on this information, first calculate the energy that would be used by this compact washing machine in a year. Then calculate the yearly energy cost. $3.27 $15.34 $19.00 $178.40

Explain the pros and cons of using natural surface water as source of water for domestic use.
a). Describe what type of forces are acted upon a body, when it moves through a moving fluid (b). Explain about basic difference in functioning of Francis and Pelton Turbines.
Consider a 400-MW, 32 percent efficient coal-fired power plant that uses cooling water withdrawn from a nearby river (with an upstream flow of 10-m3/s and temperature 20 °C) to take care of waste heat. The heat content of the coal is 8,000 Btu/lb, the carbon content is 60% by mass, and the sulfur content is 2% by mass. How much electricity (in kWh/yr) would the plant produce each year? How many pounds per hour of coal would need to be burned at the plant? Estimate the annual carbon emissions from the plant (in metric tons C/year). If the cooling water is only allowed to rise in temperature by 10 °C, what flow rate (in m3/s) from the stream would be required? What would be the river temperature if all the waste heat was transferred to the river water assuming no heat losses during transfer? Estimate the hourly SO2 emissions (in kg/h) from the plant assuming that all the sulfur is oxidized to SO2 during combustion.
Hello, I need some help with this question 1 gallon of oil = 4.1 therm and 1 therm costs $1.40 You realized you had 3,600,000 BTU heat loss over a winter month. (1 therm = 100,000 BTU) How much money has been wasted in heat loss?
